Abstract

La présente invention concerne des granulats à pigments qui se caractérisent en ce qu'ils se basent sur une matière de support qui est recouverte d'un ou de plusieurs pigments à effet en forme de paillettes au moyen d'un adhésif. Les granulats à pigments de l'invention trouvent des applications de préférence pour la pigmentation de matières d'application, notamment de peintures, d'enduits, de laques, de laques en poudres, de matières plastiques, et en particulier de granulat à dispersion et de granulat à effet, par ex. pour la décoration de papiers peints.
